MACHINE FOR FLAT-HOEING AND THINNING TURNIPS.

SPEGIFICATION forming part of Letters Patent N 0. 679,090, dated July23, 1901. I

Application filed March 11, 1901. Serial No. 50,719. (No model.)

To all whom it may concern.-

Be it known that I, PHILIP JOSEPH PAR- MITER, a subject of the King ofGreat Britain, residing at Ansty, Salisbury, Wilts, England, haveinvented a new and useful Machine for Flat-Hoeing and Thinning Turnipsand other Roots, of which the following is a specification.

My invention relates to an improved implement or machine for hoeing andthinning turnips and other plants, the chief object of my inventionbeing to provide a machine that will single or thin turnips or otherplants sown in rows.

In carrying out my invention I provide a revolving wheel or disk havinga series of arms with hoes at their extremities, the said disk beingarranged in such a position and at such an angle that it revolves bycontact with the ground during the forward movement of the implement,thereby imparting to the hoes a combined rotary and forward movementthrough the row of roots to be thinned.

In the accompanying drawings, Figure l is a side elevation of animplement constructed according to my invention, and Fig. 2 is a plan.Fig. 3 is a View of a detail.

The main frame of the machine comprises a cross-bar a and the beam b,the said beam at its front end being bifurcated and pivoted upon pins 00, carried in hangers d cl, secured to the cross-bar a by the clips e 6,so that the said beam is capable of moving more or less uponthe pins 0c.

f f are the traveling wheels, the axles of which are carried by verticalstandards g g, attached to the cross-bar a by clips h h.

11 71 are the draft-shafts, which are secured to the cross-bar a, and jis a shaft-stay, which is secured to a bracket k, fixed upon thecrossbar a. This bracket also carries a notched segment Z, in connectionwith which is a pivoted lever m, having a spring-catch 71, designed toengage with the notches in the segment Z for a purpose hereinafterdescribed.

0 is a supplemental frame pivoted upon the pins 0 c, as clearly shown inFig. 3, the said supplemental frame having its two ends bent downwardlyto form stems p p, to which fiat hoes q q can be bolted. The rear end 0of the said supplemental frame is arranged be neath but out of contactwith a pin 1' in the with the lever on by links 3, so that it is lockedin position when in work, and when the said lever m is raised it willturn the hoes q q out of the ground and also lift the beam Z). It willbe noticed, however, that owing to the fact that the end 0 of thesupplemental frame 0 is arranged beneath the under side of the pin r onthe beam 19 the said beam can be moved independently of the supplementalframe.

1 is my disk wheel, which comprises a se ries of arms a u, attached to asuitable boss and having at their outer ends the plates or hoes o o. Thesaid wheel 2! is mounted upon an axis w, which is attached to thebeam 1) by a clip y, the said axis being arranged in such relation tothe beam that the disk wheel only comes into contact with the ground fora short portion of its circumference at one side of the rear half of thewheel, so that as the implement is caused to travel the contact of thewheel with the ground will cause the same to rotate without -thenecessity for providing driving mechanism.

WVith the construction hereinbefore described it will be understood thatwhen the implement is moved forward the flat hoes q q will work or cleanthe space between the rows to be thinned, while those hoes 1) 'U o ofthe wheel 25 which are in contact with the ground will as the saidwheelrotates in the direction of the arrow, Fig. 2, move across the rows, andas each hoe while actually in the row (which in Fig.2 is indicated bythe dot-anddash lines) moves forward, owing to the forward movement ofthe implement, it follows that it will continue to cut out plants fromthe row until the rotation of the wheel t has moved it out of the row.The interval be tween the points at which one hoe 11 leaves the row andthe next adjacent hoe enters the row is the amount of the row which isleft untouched by the hoes.

z is a spring connecting the beam 12 to the bar a, so that the weight ofthe beam 7) and wheel 25 is carried by the said bar a. The strength ofthis spring a is so regulated as to hold the beam or and the wheel tclear of the ground and the row of plants to be thinned,

and when so held the wheel 25 does not revolve. When it is intended forthe hoe-wheel to cut the row of plants, the attendant presses it down bymeans of the handle at the rear end of the wheel-beam, when it revolvesand cuts out the roots required. The beam I), carrying the disk, isoperated without interfering with the flat hoes g.

If both the wheel t and the flat hoes q q are to be raised out of theground, the springcatch at is disengaged from the notch in the segment Zand placed into one of the other notches in a manner which will bereadily understood.

Having now particularly described and ascertaincd the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In an implement or machine for thinning turnips andother plan ts, a wheel or disk havin g a series of arms carrying hoes attheir extremities and arranged at an angle with the ground so that thehoes at one portion of the circumference of the wheel only are incontact with the ground at one time whereby as the implement is causedto travel a rotary motion will be imparted to the said wheel or diskowing to its contact with the ground, giving the hoes a combined rotaryand forward cut through the row of plants, substantially as described.

2. In an implement or machine for thinning turnips and other plants, thecombination of a rotary wheel having peripheral hoes and adapted to bedriven by contact with the ground and flat hoes for Working the groundbetween the rows to be thinned, substantially as described.

3. In a machine for thinning plants,v the combination with the frame andits supporting-wheels, of a beam pivotally connected with said frame, arevoluble wheel or disk having its axis secured to said beam, andarranged in an inclined position with respect to the surface of theground, a spring normally holding said wheel out of contact with theground and means for depressing said wheel into engagement with theground and a series of hoes carried by peripheral portions of said wheelor disk, substantially as described.

4. In a machine for thinning plants, the combination with the main frameand its supporting-wheels, of a beam pivotally connected to said frame,a revoluble Wheel or disk carried by said beam and having its axisarranged in an inclined position with respect to the surface of theground, a series of hoes carried by said wheel or disk, a supplementalframe pivotally connected with the main frame, hoes carried by saidsupplemental frame, means for adj usting said supplemental frame, andindependent means for raising and lowering said beam, substantially asdescribed.

5. In a machine for thinning plants, the combination with the main frameand its supporting-wheels, of a beam pivotally connect ed with said mainframe, a revoluble wheel carried by said beam having its axis arrangedin an inclined position with respect to the surface of the ground, aseries of hoes carried by said disk or wheel, a supplemental framepivotally connected with said main frame, hoes connected with saidsupplemental frame, said supplemental frame being provided with avertically-movable part adapted to engage a part connected with the saidbeam, to raise said beam, adjustable lifting mechanism connected to saidsupplemental frame, and independent means for raising and lowering saidbeam, substantially as described.

6; In a machine for thinning plants, the combination with the main frameand its supporting-wheels, of a beam pivotally connected with said mainframe, a revoluble wheel carried by said beam having its axis arrangedin an inclined position with respect to the surface of the ground, aseries of hoes carried by said disk or wheel, a supplemental framepivotally connected with said main frame, hoes connected with saidsupplemental frame, said supplemental frame being provided with avertically-movable part adapted to engage a part connected with the saidbeam, to raise said beam, adjustable lifting mechanism connected to saidsupplemental frame, a spring connected to said beam to hold said disk orwheel normally out of contact with the ground, and means for depressingsaid beam to lower the wheel into cont-act with the ground,substantially as described.
